Sure it can work, just change the resistors so, that the gate voltage on Q1 is 2~3V higher compared to the one with virtual ground. This will lift-up the source voltage on Q1, hence the DAC output voltage.

Already build 3 massive power supplies , the input receiver...
The TDA still not arrived

I take the occasion for a question that is pretty interesting for the thread:
the absolute output phase:
I noticed in different projects around the internet that just one case does an exception regarding the pins in the differential input receiver from the SPDIF. The pins are 9 and 10 of the CS8412.
Almost all projects sets the pin 10 (after the cap) at ground , and the pin 9 (after the cap) at the signal.
The TNT-audio CONVERTUS does the opposite: pin 9 at ground and pin 10 at signal.
Does this help to restore the absolute phase at the output of the DAC, since I read at the NONOZ2 DAC page that the TDA1543 inverts the phase?
